It could be very useful if it were possible to send a "read-only" workspace link, where the user doesn't see the left hand-side menu for elements and can modify only settings inside the dashboard: time range, order of elements in a table, read numbers on charts...
An option "open in edit mode" or something like that could be added at the top to show the different menus. Alternatively, it could be replaced with a "copy in your workspace" if we do not want the recipient to modify the original workspace.
Moreover, a read-only workspace would be lighter to load and to scroll. PDF and .csv download could be left as well.
